Application filed February 25p, 1925. Serial No. 11,495.

This invention relates to a surgical instrument, technically known as or proctoscope to be used tion of the rectum, pelvic colon, 5 flexure, descending colon, and

channels orducts, for locating permitting curative ological ti'oubles and a siginoidoscopc in the examinasiginoid other canals, possible pathreinedies to be applied to the affected parts. The main object is to provide a device ot this character which may be inserted into the affected duct with the least possible irritation or inconvenience to the patient and at the saine time to provide said device with means whereby the affected part may located and properly treated accurately through an opening in the implement while the latter still remains in the duct.

channel or Another object to provide the distal end of the device with beak or obturator of' but slightly concaved side and convexed so that it may be used a longitudinally tapered rounded cross section longitudinally on one along its opposite side more effectively for distending or dilating strictures or othercontracted portions oi the channel or duct into which it is inserted without liability of lacerating the tissue walls thereof. i

Another object is to provide the proximal end or hilt of the outer tube or sheath of the device with a suitable cup-guard or stop plate constructed in such manner as to support the device against lateral rolling displacement upon a table and by hand or equivalent support in a convenient position for grasping when not in actual use, and to prevent excessive entrance into the duct.

A further object is to provide the vdistal end of the device with a relatively small but powerful electric lamp manner as to arranged in such direct its rays over a relatively wide range of the channel or duct into which -the device is inserted when the closed beak or obturator is removed without obstructing a clear vision of the walls of said channel or duct through the proximal gated tube.

until the shoulders 251-- ott the section M27- ride against the shoulders -30e of the section 47- and then by continuing the inward pressure of the section #27 f the shoulders -31- will ride over the shoulders -30 until they enter the recesses -`-31- at which time the shoulders -30- will enter the recesses -30-, it beingunderstood that the walls of the distal end of the slot -19- are sufficiently resilient to permit this interlocking engagement oit the shoulders lta nd -ilyin their respective recesses --'31- and -30 and that when the parts are thus interlocked the beveled edges #2% ot' the section -7- tit closely against the corresponding beveled edges 29- of the section -27-- thereby producing a subst-anA tially smooth external surface at the joints.

The resiliency of the opposite walls of the slot -l9- serve to yieldingly hold the parts -7 and 2T in interlocking engagement against relative axial rotary movement and also hold them in axial alinement but when the tube #7m with the obturator 9U-- interlock with its distal end inserted in the outer tube or sheath the distal end of ythe latter extends beyond the locking joint between the sections 7 and 2T- and additionally hold them in interlocking engagement against relative axial or circuml'erential displacement. Y i

Av small mirrow 32 is mounted on the distal end of a supporting ystem which, in turn7 is slidably and rotatably mounted in a relatively small guide tube B4-7 the latter being lengthwise of and within the distal end of the tubular section WT and rigidly secured thereto by brazing or equivalent Yfastening means.

The mirror 3.2- is suiiiciently small to pass within the tubular end of the beak -27- and is preferably disposed at an obtuse angle with the. stem end adjustable rotarily as well as axially so as to reiiect the rays of the lamp #22# through the open side of the slot to enable the operator to examine more closely the affected part into which the device is inserted through the open proximal end of said device or through the windows 1C- or -18 as may be desired.

The distal end of the sec-tion -QT-e is preferably tapered and closed atits smaller end but its outer surface is smoothed and rounded in cross section, one side thereof being concave longitudinally at --35-A while the opposite side is preferably convexed at 3(5 easily distend or dilate the aectedpart into which is inserted without excessive irritation or inconvenience to the patient.

The hilt`8- of the tube -T-e carrying the electric conducting tube -25- is provided with an outwardly extending nipple -37- containing the termina-l electric contact member #3S- of the conductor -22- of the lamp and also adapted to receive a suitable coupling by which it may be connected toa source of electrical energy. i

This coupling comprises a metal' head H39- having reduced tubular extension which permits lthe beakV to more- -40- adapted to slide over and upon the nipple 3T- said head being also provided with the usual axially yielding contact mem befr --L1- for engagement with the contact 38 for completing the closing of the lamp circuit when the parts are assembled.

A sleeve -42- is slidable axially of and upon Ythe head and is provided at its inner end with an inturned flange 4L3- surrounding the reduced end -ei0 to form a set Vfor 'a reti-acting spring -44-- which is interposed between the `flange .-flf and inner end otthe head -39-ilior normally urging the sleeve inwardly. Y i ,j

The reduced portion 40 of the head B9- is provided withy a slot 45.- extending lengthwise thereoil from its inner end for receiving a radially projecting pin -Jf(--` on the adjacent side of the nipple o" ,one of the walls of said slot being provided with a laterally projecting recess -47-- which is also adapted to receive the pin for locking the reduced portion -lkon the nipple .-37- when the coupling is assembled thereon. i

The sleeve -42 is provided with anaxi# ally projecting tongue H48- slidable in the slot -45- across the lateral recess f4.7- as the sleeve 4l-2- is moved endwise and holds the sleeve and head 39 against relative turning movement,` said sleeve being provided with a screw projecting into an annular groove in the head 89- as shownv in Figure 2 to prevent endwise displacement of the sleeve from the head.

The inner end of the tongue is provided with a cam iace -5()- which, when the coupling is placed upon the nipple 37- rides against the pin 4G- thereby `forcing the sleeve 4t2- outwardly against the action ot its retracting spring -44tuntil the recess e7- is registered with said pin at which time the pin is caused to enter the recess at one side of the tongue 4S-there by allowing the sleeve 4Q- and its tongue to be forced inwardly by the spring 411- to lock the pin in the recess and to hold the coupling in operative connection with the To remove the coupling from the nipple it is simply necessary to draw the sleeve -42- outwardly by hand minst the notion of the spring -44, there 5f withchaxving the tongue -48- bevond the pin -4T-- und allowing the latter to enter the slot 45N and pass through the-open end of the slot.

An .air inlet nipple -5lis secured to the hilt of the tubular 1sreotio1i-7 and ,iS adapted vto be connected by a flexible pipe 52- to :no air eompreseor for sulwlying, air to the interior of the tubes in ease it may be desired to further listend or dilate the colon or other duety into which the instrument is inserted.

When the verrioinl .sect-ions of the device are assembled in the mann-er shown in F ig:- unes l and 2 they may be inserted to an)v degree indicated by the gradnauions (3- into the colon or other duet to be examined between the guard plute -3- and distal end of the section -l6- and after the all'erted part has been dietended the required amount t'or examination the tubular sheath -1- may be left in the duet and the Heetion -T-- together with the beak -S- and other partel carried fthereh may be entirely withdram'n from the sheath to permit: the removal of the heal: or obturator 3tS-.

Immediately following?r the renuival ot' the beak the. inner' tubulaiseetion 7- may be reinserted in the sheath 1- and its lainp circuit nonnen-ted to a source of eleotric energy for illuminating the interior of the ducty and permitting u more thorough examination of the various .parte thereofrit being` understood that the rays of light from the lamp -22- .are free to radiate through the opening 19- aided by the mirror The parte` to he examined may then be inspected though the opening in the proximal end of the tube -7- with or withoutthe use of either of the lens 16- or -18-4 1 ,semer Then the aeoted part of the colon or duet. is located suitable treatment manY be applied till-rough the tube by simplyv adjusting the tubes to bring;r the *opening l9- into registration with the ntl'ected part.

Then the diseased ,part is properly treated the tubes may be withdrawn and separated one from another for properly cleansing and sterilizing ready for repetition of the operation.
